Spit mk V carried 2x250lb bombs one under each wing.
Spit mk VIII
"A maximum external bomb load of 1,000 pounds (1 × 500 lb (230 kg) bomb attached to the centre bombrack plus 2 × 250 lb (110 kg) bombs, one under each wing) could be carried." Shores and Thomas 2008, pp.586, 607
Spit mk IX / XVI
During early 1945, some Spitfire IXEs and XVIEs of 74 Squadron were fitted with a single RP-3 rocket under each wing. This was believed to be the only RAF Spitfire unit to use rockets operationally during the Second World War.
"In any case all the Spit IX Squadrons operated most of the time as fighter-bombers." Pierre Clostermann"
We have no bombs whatsoever for the mk IX
I think what I would like to wish for are the differences between the C and E wing variants to be optional from the hangar. The E wing also enables 4 x 20mm but i'm not to bothered about that particular option (will handle like a pig) but it should be available or perkable. This thread is about the rightful addition of bombs though so i'm not going to go down that road.
